APPARATUS FOR COATING TEXTILE THREADS 'WITH A SOLID SUBSTANCE.

Application led January 13, 1823. Serial No. 612,539.

To all whom t may concern:

Be it known that I, HANS Sorrwnrrnn, a Swiss citizen, residing at Horgen, in the Canton of Zurich, vented a new and useful Improvement in Apparatus for Coating Textile Threads with afSolid Substance, of which the following is a specification. p

This invention relates to apparatus for coating textile threads with a solid substance, chiefiy parafline, in which the thread is drawn between the two substance blocks which are pressed together by springs and are rotated by the pull on the thread by means of a toothed wheel drive.

According to my invention the carriers of the substance blocks together with the toothed wheel belonging thereto is arranged oscillatable in a forward direction on the 0 bracket of the apparatus for the purpose of enabling replacement of the substance blocks from the front of the apparatus without ref quiring additional room.

The previously known methodL of chang ingthe substance blocks from the side of the apparatus was inconvenient and required much room.

I attain the objects aimed 4at by the mechanism illustrated in the accompanying draw- 0 ings, in which- Figure 1 is a front elevation and Figure 2 a left-hand side elevation ofrone constructional example, showing the substance blocks in operative position.

'35 Figure 3 is a similar elevation to Figure 1 and Figure 4 a similar elevation to Figure 2, but partly in vertical section and showing the substance blocks swung 90 degrees forwards. f

Figures 5 and 6 are horizontal sections on line 5-5 of Figure 1, the substance blocks and their carrier sleeve being removed in Figure 6.

Figure 7 is a detached front elevation,

Figure 8 is a detached side elevation, and

Figure 9 is a plan view illustrating another construction.

Referring to Figures 1 to 6, an angular apparatus bracket 2 is adjustably fixed by a 0 set screw to the horizontal supporting rod 1.

The horizontal part of the bracket 2 carries the thread guide 4 and the thread guiding roller 5, whilst the vertical part of the bracket 2 carries an axle pin 6 on which a boss 7 is mounted, the boss 7 being provided Switzerland, have in-y with a pinion 8 and a guiding and driving pulley f AV semi-circular disc 12 provided with apertures 10 and a rim flange 13, and serving to carry the substanceblocks, for example paraiiine blocksll, has two diametrically opposite lugs 14 having bearing cavities 15 for two pivot screws 17 screwed into lugs 16 formed on the vertical part of the bracket 2. At the axis of the-,disc y12 there is fixed an axle pin 18 onto which a sleeve 19 is pushed. There is fixed to the sleeve 19 one endof a tube 20, Figure 6, which is swelled out between its ends and divided into kresilient laminae by longitudinal slits. The boss 21 of the wheel 22 which meshes with the pinion 8 is fixed on the sleeve 20.

Onto the spring tube 20 is pushed the carkrier 'sleeve 24, and the resilient laminae -of the tube 2O produces a rigid connection between the tube 20 and the sleeve 24. The sleeve 24 has a cylindrical bore, is externally of square cross-sectionand is of resistant material, for example, porcelain. The subc 26, Figures 3 and 5, pushed into grooves 25 in the sleeve 24. The sleeve 24 is also provided withan annular groove 23 whichlies inthe plane of contact of the blocks 11 and L the'thread 28 is drawn between the blocks 11 and at the same time engages the groove 23 in the sleeve 24. p f

- When the apparatus is in operation, the disc 12 together with the substance blocks 11 are in the positions illustrated in Figures 1 and 2, the disc 12 being fixed in the working position by means of a vscrew-threaded pin k32 yscrewed into alug 29 and engaging an eye lug 30 on the disc 12 and connected by a chain 31. The pull on the thread sets the pulley 9, the toothed gearing 8, 22, the sleeve 19, the tube 20 and therefore the substance blocks 11 in rotation for the purpose of effecting a uniform using up of the blocks 11.

After the blocks 11 have been used up, the pin 32 is withdrawn and the disc 12 is oscillated in a forward and sidewise direction into the position illustrated in Figures 3 and 4. The carrier sleeve 24 is then drawn in a forward direction olf the spring tube and has new substance blocks 11 placed on it, whereupon itis again pushed on to the spring tube 20. The disc 12 and the new substance blocks 1l are then again oscillated back into their working positions and secured therein. On the forwards and backwards oscillation of the disc l2 the wheel 22 comes out of and into engagement with the pinion 8. It will be appreciated that for renewing substance blocks no additional room is yrequired as is necessary inthe case where renewal of the blocks takes place Tfrom the side. rIhus a larger number-of apparatus than hitherto lcan be mounted on the carrying rod. Furthermore the renewal of the blocks from the front is handier than renewal from the side.

In the construction illustrated in Figures 7 to 9 the parts are the same *as described with reference to the first vconstruction with the exception that the thread guiding roller 5 is higher vand is arranged above the thread clearer provided on the horizontal 'part of thebracket v2. The thread clearer has a stir rup 38 secured to the said part and `carrying on its arms jaws 34 adapted to 'be adjusted by means of screws and Serving `to clear the th-read 28 passing between thein. The cleared thread then passes to the substance blocks 1-1.
